1.General:
To solve the problem of white stripes caused by the toner cartridge, the PCU-ROM
software is modified. After completion of warm-up or printing operation, the new software
makes the developing roller rotate in a reverse direction by approximately 1.9mm to
prevent the toner from adhering to the blade in the toner cartridge.

3.Description:
1) Update PCU-ROM to the version presented in the table below.
3) Also, update other ROMs to the versions in the table below.
4) After updating, change value of “Q item” from “0” to “72” using Sim44-4.

Changes : 1. Change of Specifications
1. The following changes have been implemented to cope with white stripes.
1) When the warming up and printing performance are completed, DV roller is made
rotate slightly in reverse by about 1.9mm and the accumulated toner at the pressure
contact area between the blade and DV roller in cartridge will be removed. Then
toner will be prevented from sticking to blade in toner cartridge. The item "R" has
been added to Sim44-4 regarding this function.
* The setting of R = 0 (Default) means permission of reverse rotation and the setting
of R = 1 means prohibition of reverse rotation.
2) The number of executions of high - density process control will be controlled when
the power is put on (includes when the power comes back from auto power shut off)
and when the machine has been left with no effect of auto power shut off.
The item "Q" has been added to Sim44-4 to set the execution timing of process
control.
* The setting of Q has been changed to "72" because the setting of Q = 0 (Default) is
the same specification of function as before.
4.Action:
1. Machine: From the middle of January 2006 production.
Countermeasure to prevent white stripes caused
by the toner cartridge.
